To @ZZ whom 'it may concern:

Be it known that I, LYMAN RICHARDS SWETT, acitizen of theUnited-States,"resid ing at Boston, in the' county of Suffolk and Stateof Massachusetts, have invented certain new and useful Improvements inTwo- Compartment Envelops and -I do hereby declare the following-to e afull, clear, and eX- act description of the invention, such as willlenable others skilled in the art to which it apl edge, and the other endsection has an'end adhesive sealing-lap, so that when the end sectionsare folded, one upon the other upon the middle section the said adhesivelaps are se cured to the lapped end sections in a novel manner to formthe 'two compartments, one

opening at the side and the other at the end of the envelop, the lapsbeing soarraged as to form said compartments by the two end sectionsonly having equal length with the middle section, thus saving cost inpaper and requiring little time to fold and unite the two end sections,as cheapness and quickness in making such envelope is the importantmatter to the trade.

Referring to the accom anying drawings, Figure 1 shows the blank gomwhich the envelop is formed.' Fig. 2 shows the blank with one of its endsections 4 folded on the middle section. Fig. 3 is a longitudinalsection on the line 1 of Fig. 2. Fig. 4 is a transverse section on theline 2 of Fig. 2. Fig 5 is a like section showing the side edge adhesivelap 2 of the middle section turned down upon the vedge of the folded endsection. Fig. 6 is a View like Fig. 2, showing the side edge lap 5 ofthe folded end section turned down upon it. Fig. 7 shows the lother endsection 6 folded upon the folded end section, the sealingla s of the twocompartments being open. Fig. 8 shows the reverse side of Fig. 7. F ig.9 is atransvei'se section on the line 3 of Fig. 7.' F ig. 10 is alongitudinal section on the line 4 of Fig. 7. A

I have shown and prefer to form the e'nvelop from a single blank, butobviously separate pasted sections may form the blank and the envelop.The blank'is a strip of paper the Width of the envelop divided intothree the sections of equal length on the folding-lines a and b, themiddle section 1 having a narrow adhesive la 2 at one edge and asealing-lap 3 at its opposite edge, One ofthe end sections 4 has anarrow adhesive lap 5 at the edge in alinemeiit with the sealing-lap 3lof the middle section, and the other end section 6 has an endsealing-lap 7. With those two folding-sectiens and the four, narrowadhesive laps disposed as described the envelopis formed With the twocompartments as follows: The sec- -tion 4 is folded-upon the middlesection, the

adhesive lap 2 of which is folded upon the edge of the said foldedsection 4, whilethe adhesive lap 5 of said section 4 is folded over andupon said section, as in Fig. 6. These laps 2 and 5 are provided with anadhesive substance on their upturned sides, and the section 6 is folded.over upon the section 4 and secured to the lap '2 of the section 1 andthe edge 8 and form the pocket-opening 9 at the overhanging end lap 7between the joiningsurfaces of the sectlons 4 and 6 when folded. Thisleaves the adhesive side edge lap 3 of the section l open to form theopening at 11, Fig. 9, for the pocket l2', opening at' the'side of theenvelop. By this construction it will be noted that the end section 4 ispreferably not secured to middley section 1 and that the end section 6is secured to the adhesive lap 2 of the middle section and to theadhesive lap 5 of the folded section 4, thereby securing the backsection 6 to both the front and the inner sections 1 and 4 and causingthe inner folded section to reinforce the front and back ofthe envelopby two narrow laps.

The envelop may be used for church and commercial purposes, and I haveindicated that the back compartment is for missions and benevolence andthe front compartment for current expenses of church or Sundayschool.
